Background

The aim of this study was to prospectively compare the diagnostic accuracy of videoendoscopy, with and without Lugol staining, for the detection of esophageal cancer in alcoholic or smoking patients older than 40 years.

Methods

Daily alcohol and tobacco consumption and overt and latent symptoms were noted.

The 158 patients included were examined by videoendoscopy and with Lugol dye.

Results

The mean consumption of alcohol and tobacco was 86 ± 49 gm/day for 26 ± 11 years, and 30 ± 18 pack-years, respectively.
